I have P3D v4.5 installed with ORBX FTX Global and OpenLC North America.

I recently installed CYYZ 1.5. I was recently having issues with the terminal near the cargo area. Most of it was disappearing or was just floating weirdly.

I was also having issues around the airport with zones appearing with only default night textures. I read in another post that the landclass would be at fault.

I disabled the landclass and all the errors went away - including the missing textures at the terminal (which I find very odd). This is a shame as I enjoyed the additional buildings around the airport. That said, I rather have a working airport...

I assume this is related to a conflict between FlyTampa CYYZ and the ORBX FTX OpenLC North America?

I was wondering if there was a fix for that...

See pictures below for the additional details... Any assistance would be much appreciated.

Nice find. I have no idea how that LC would conflict with PBR terminals, seems completely unrelated to me. If you have ORBX NA, disabling the LC entry is the best option anyway. The LC option is only there because stock FSx/P3D CYYZ surroundings look like rural farmland.

This might sound like a stupid question, but is there a way to just keep the additional buildings around the airport without the LC? I understand the logic behind the enhancement to the default LC, and that it would enter into conflict with the Orbx LC... It's the buildings that I recognize from real life that added that "heeeyyy nice!"

The surrounding Photoscenery and custom Buildings are kept when you disable/delete our LC file. The LC file just alters the landclass miles around the airport and populates it with generic autogen. If you have ORBX, you already have both the custom buildings + surrounding suburbs.
